FAST (Five-hundred-meter Aperture Spherical radio Telescope) focus cabin is driven by 6 cables, moving on a spherical cap of ~ 206 meters in diameter. In order to achieve the required pointing accuracy of the telescope by positioning and orienting the receiver properly, X/Y positioner and Stewart manipulator are employed. In addition, reaction mass dampers (RMD) are investigated to depress the cabin's vibrations at high frequencies. In this paper, a simulation model of FAST focus cabin is created. Control simulation is carried out to evaluate control performance of the focus cabin. As a result of this simulation work, X/Y positioner, Stewart manipulator and reaction mass dampers show satisfied performance in compensating the residual position and orientation errors and depressing vibrations. The simulation work approves the feasibility of this engineering concept, and also paves an efficient approach for optimization in the future design work.
